The New Jersey-based band announced early Saturday that “it has come time for it to end.” The foursome thanked their fans in a statement and said the experience was “a true blessing.”

My Chemical Romance’s sound is a mix of alternative, punk rock and pop. They released their debut album in 2002 but really made a splash in 2004 with the platinum-selling Three Cheers for Sweet Revenge. It featured the top-40 hit “Helena.”

They followed that with another platinum effort in 2006 with The Black Parade, earning their first top-10 pop hit with “Welcome to the Black Parade.”

Their last album was in 2010.

The NME reports that thousands of grieving MCR fans have signed a petition calling on the group to hold “one last world tour to say goodbye to their fans.”

“They ended so abruptly without saying goodbye to their fans properly, and the MCRmy is upset,” petition organiser Cameron Lee wrote. “They need to do it correctly if they’re going to do it at all.”
